Abstract :
The optimization of most pesticide and fertilizer applications is based on overall grove conditions. In this work we propose a measurement system based on a ground laser scanner to estimate the volume of the trees and then extrapolate their foliage surface in real-time. Tests with pear trees demonstrated that the relation between the volume and the foliage can be interpreted as linear with a coefficient of correlation (R) of 0.81 and the foliar surface can be estimated with an average error less than 5%
